Q. Primary amine ($RNH_{2}$) reacts with nitrous acid to give
A) $RNH_{3}^{+}NO_{2}$
B) $ROH$
C) $ROR$
D) None of these
Explanation
(b)
1${^\circ}$aliphatic amines on reduction with $HNO_{2}$ form alcohol and evolve $N_{2}.$
$RNH_{2} + HONO\overset{{NaNO}_{2} - HCI}{\rightarrow}ROH + N_{2} + H_{2}$
